The preface to this work is a good summary what this piece is:

"This piece is a work that is difficult to classify. It could be conceived as a board game, an aleatoric
chamber piece, a performative piece, a musical, instrumental theatre or, to put it briefly, an
“Interwerk”. It should also be noted that this piece is an experimental work. It therefore allows the
performers more freedom than other compositions."

The piece is played by any number of musicians and accompanied by a gamemaster. 
The two main components of the piece are the game board and the music piece. Both are divided into four zones. In the case of the game board, the zones are also divided into 13 fields.

The gamemaster moves the pieces around the board. Each piece is assigned to a musician. If a piece stands on a plattform it can trigger different actions, like:
playing at half tempo, reading staves from right to left, the figure changes zones, or the player must hop 13 times. 

Auch beeinflusst das Spielbrett die Musik, die gespielt wird. So wird je nach dem, in welcher Zone sich die Figur eines Spielers befindet, ein anderer Teil der Partitur gespielt.

The different zones in the score also have different topics. The first zone has the topic "melody", the second one "harmony", the third one "rhythm" and the fourth one "musicality". In the first two zones a free notation is used. In the third zone is the standart western notation used. The fourth zone is made up of boxes distributed throughout the score. The musicians has to choose which the individual framed musical snippets is played as a reaction to what is happening around them.

The end of this work is determined by the position of the pieces or by the 13-cards. The game ends when all the pieces are on a 13-square or when all five 13-cards are turned over.
There are also interesting special rules like the yellow and red card. If a player picks up the yellow card, it cancels the current position or action. When a red card is picked up, one of the five 13-cards is turned over. 


Minecraft 12-Tone random generator

The central element in the 12-tone generator is a module that has the function of playing a tone and then preventing that tone from being repeated. This is regulated by the position of the sand block. When it is at the top, it forwards the signal.

Simultaneously the mechanism checks whether all twelve tones have already been played. If this is the case, the entire generator is reset and the next series of twelve tones is used.
In Minecraft there is a building block that drops a random component into the game, the so-called dropper (on the right in the picture). This dropper ejects one of two items. Depending on which item it ejects, a different signal is passed on.

13-competitive Minecraft version

The two most important aspects of the Interwerk, which is both a game and a piece of music can be guessed by its name. Firstly, there should be a winner at the end, and secondly, the entire work should take place in Minecraft. It has been built on the ScoreFollower Minecraft server and is based on composition 13. The big challenge in designing the work was that the server is played in survival mode. Thus, every building block has to be collected from the surrounding environment, crafted and placed one by one.
The building process starts with terraforming to make space for the construction. Then the layout of the field is determined and the loops are placed under the respective platforms. Next, the design of the game board is laid out. The last step is the design and construction of the exterior and interior.

The game has a total of twenty-six platforms. Two of these always trigger the same loop. The two platforms that do not trigger a loop are the start and finish. Each platform also has a dropper right next to it, which is filled with nine differently named pieces of paper. These are labelled with different numbers. By pressing a button, a piece of paper is ejected and the respective player must move forwards or backwards by the corresponding number of the spaces.

The dice droppers are filled as follows:

The loops are connected to the following platforms:

Start of the game and turn

The order of the players is determined by activating the colour dropper. The player whose colour is dealt first is also the first player to start. This process is repeated until all player colours have been dealt and the order has been determined.
Each player's turn consists of activating the respective dice dropper on the platform, putting the paper back into the dropper and moving the playing piece forwards or backwards. 
If a piece enters a platform on which another piece is already standing, the standing player must move back to the next free platform, but no further than the starting square.

End of the game and objective 


The objective of the game is to be the first to reach the final platform. The game ends as soon as the first player reaches the finish platform. All players must then leave the pressure plates or the respective platforms as quickly as possible.
